Accessibility overview

This section describes how accessibility is implemented in Flexmonster and how to use its accessibility features in your project.

High-contrast CSS theme

You can switch to a high-contrast theme by selecting the grid and pressing Ctrl + Alt + H (Command + Option + H on macOS).

As a high-contrast theme, Flexmonster uses the CSS file from the theme/accessible/ folder. It has more contrasting colors than the default theme. Besides, this theme is compatible with high-contrast modes Live example.

Setting a custom high-contrast theme

You can set a custom high-contrast theme using the accessibility.highContrastTheme property in the new Flexmonster() API call:

const pivot = new Flexmonster({
  container: "pivotContainer",
  componentFolder: "flexmonster/",
  accessibility: {
    // Path is relative to the componentFolder
    highContrastTheme: "theme/yourTheme/flexmonster.min.css",
  },
  report: {
    // ...
  }
});

Now the theme from the accessibility.highContrastTheme will be applied when switching to a high-contrast theme.

You can also set the high-contrast theme as the main one by adding a reference to its minified CSS file:

<link
 rel="stylesheet"
 type="text/css"
 href="flexmonster/theme/yourTheme/flexmonster.min.css"
/>

See our guide on creating a custom theme for further details.

Compatibility with screen readers

Flexmonster implements WAI-ARIA (Web Accessibility Initiative — Accessible Rich Internet Applications) to ensure compatibility with screen readers. WAI-ARIA requires adding specific HTML attributes to interface elements to define their roles, states, and relationships.

Information specified in these attributes helps screen readers interpret the structure of the UI more accurately, giving users a complete understanding of what they are working with.
